ST. JOHNSBURY — Four people are facing felony drug charges in connection with an alleged heroin distribution ring in northern Vermont.

The Vermont Drug Task Force Police says two and two women were arrested Friday in connection with the June 6 seizure of 540 bags of heroin police say were being brought from southern New England to Vermont to be distributed.

Fifty-three-year-old Deborah Clark of St. Johnsbury, 27-year-old Dillon Garand of Barnet, 53-year-old Kevin Palmer of Lyndon, and Clark’s daughter, 24-year-old Brittany Clark of St. Johnsbury, pleaded not guilty to the charges Friday in criminal court in St. Johnsbury.

Palmer is being held on $200,000 bail, with Deborah Clark and Garand each being held on $100,000 bail. Brittany Clark was released after posting a $1,000 unsecured appearance bond.

Citing a police affidavit, the Caledonian-Record reported that police are alleging that Deborah Clark was selling heroin out of her St. Johnsbury apartment that was brought into the state from Connecticut and Massachusetts.

Police found the heroin in a vehicle driven by Garand in which Palmer was a passenger that was traveling north on Interstate 91 and was stopped in Lyndon shortly after midnight on June 6, police said.
